Verse 44

44. One should fully awaken the mind when in the lying low state, should pacify it again when tossed about; should know it particularly to be with passion, and should not shake it up when attained to equilibrium.

This verse tells us we should not sleep longer than needed and should waken fully to resume our practice. We should still the mind when distracted and keep it neutral from passions and when in equilibrium and on the right path should not seek distraction.
Or, when meditating and close to the Self one may have the sense that to surrender to sleep is to surrender to, or move closer to the Self. This is an illusion arising from effort of concentration and desire to attain to the Self. Do not sleep but continue to strive for even higher wakefulness is the exhortation.
